T0 all whom it may c0ncern:

Be it known thab I. WALTER H. Furz GER- ALD, 0f Br0oklyn in the connty 0f Kings and in the Stat;e ot New York, have invented 0ertain new and useful Improvements in Watch- Oase Centers; and I do hereby declare that; the following is a fnli, c1ear, and exacb description thereof, referenee being had to be accompanying drawings, in whieh Fignre 1 is a perspective view of my casecenter before being provided with hingerabbets. Fig. 2 is a like view of the Same at'ter beingprovided with t;he hingerabbets and operated u pon by the beveling-dies. Fig. 3 is a perspective view of said part; afer the hinges are in piaee. Fig. 4 is a like view 0f Ehe holder 01 10wer die f01 said ease-eenter. Fig. 5 is a perspecbive view of uhe beveiing-die, and Fig. 6 is a side eievation 0f said holder and die and a vertica1 eross-section of said case-center in posiion between the same.

Letters 0f like name and kind refe1 to like parts in eaeh of ehe figures.

In t;he construcbion 0f fi1ied watehcases it has heretofore been customary t0 cut I;he hingerabb'ets within theeenter and to bevel bhe sides of Ehe contiguous metal after saidcenter was otherwise completed, by whioh means the fine mebal oi' Ehe suriace was rexn0ved and the basemetai filling exposed, the resuits being that in the completed case there was ab each hinge a parla of the center which was n0t plated or covered by the fine metal, and which would quick]y tarnish. T0 1einedy this defeet, the part thus exp0sed has been afterward plated; bub a3 ii: is 110i; practieable by such xneans t0 exactiy match the eolor of Ehe covering 0f the other porions 0f the case the appearance 0f th e parb so treated has been but iibtle, if any, better than when the filling has been exp'osed. The design of 1ny invention is 110 eause a filled watch case to present a uniform appearance over izhe whole of its outer exposed sists, principally, as a new artiele 0f wann faetnre, in a filled watch-case eenter whieh has adjacent to each hingerabbet a beveied face thab is eovered by a piate which is a pai1; of and 'continuous with. the snri'acecovering 0f tl1e body 0f said ease-center, substanially as and for the purpose hereinafter speeified.

It consists, fnrther, as a new artieie 0f manufaetnre, in a fiiled watch-case center whieh is provided with a beveled face adjacent 130 each hinge-rabb% and has its hody and beveied faces covered exterioriy by a plate that is 0011 tinuous, substantialiy as and i'0r the purpose hereinalter shown.

It consi sts, furbher, as a new arbiele of manufaeture, in a filied wateh-ease center which is provided with a beveled face ad jaeeut 130 eaeh' parb oi' the cov'ering of Ehe body Cf said case- Center, subsantiaily as and for the purpose hereinalter sei; foxh.

lt; eonsists. tinaily, as a new arti(fle 0f manufacture, in a ivatch-ease center which is coustrueted principaily 0i' 0r from a base meta1, and is previded with a beveled faee adjacent t0 eaeh hinge-rabbeb. and has its body and beveied faces c0vered by a piate of relabively fine metal, which forme a continuous suri'aee over Ehe saxne, substantiaily as and for the purpose hereinafter shown and described.

In the earrying of 1ny inVent;ion into practice I preferabiy employ certain mechanism f01 producing beveied faees upon a ease-center; bub such meehanism fnrms n0 parb 0f this invention, and, ifdesired, may be omitted wholly 01 in art and ohe1 forms of mechanism used f0r the purpose nan1ed.

In the annexed drawings, A represents a ease -eenter blank which is preferably 0011- sbrucued by dies t'1r0m sheet metal, and in crossseetion has a convex exterior and a correspond ingly c0ncave interior. The caseeenter thus shaped is placed npon an anvil 01 die, B, hat snbsuantiaily conforms in cross-seetion so the iike interior forn1 of said part, and eircumferentially within t;he sanue has a lengbn of aboui; one-half ineh. Said die is suitably supported upon a base, O, so as t0 enable said ease eenter t0 be suspended therefrom, .as shown. The ease-center Abeing thus in position upon the anvildie B, a seeond die, D, having a V-shaped groove d, within its 10wer face, is caused t0 impinge upon Ehe upper porti 0n 0f the convex periphery of said casecenher, so as t0 f0rm up0n such p0iion two inciined 0r beveied faces, a, 0ne 0f which is upon each side of said center. 'Ihe porbions of said 1ower die thab are immedia-tely beneabh said faces a are correspondingly beveled, so as to cause the metal 0f said case-center to be solidly compressed between the same und thesides of 5 the groove d, and the exact shape desired t0 be given t0 said faces a.

Immediately be1ow each of the beveled faces a there is 110W cub a rabbels, a, for the reception of the hinge-tubes B, which latter are se- I0 cured in place in the usual manner after ehe periphery of the casacenter has been k nurled 01 otherwise ornamented. If desired, such ornamentation may be produced before said rabbets are cut. The operation of'forming the beveled faces in 110 manner disburbs 0x displaces the fine-metal covering which is coutinuous 0ver the who1e surface 0f said msecenter, so that said fzwes are as fullyprotected as is any othe1 portion 0f said snrface.

The mechanisxn und method hereinbefore described are covered by 21 separate application for patent, Serial N0. 202,756, filed May 20, 1886.

Having thus ful1y described my invention, what I claim is l. As 21 new article of manufaeture a fil1ed wauch-case center which has adjacent 130 each hingerabbet a beveled face that is covered by a plate which is a parb of and continuous with the surface covering 0f the body 0f said case center, substantially as and for the purpose specified.

2. As a new article of manufactnre, a filled watch-case center which is provided with a beveled face adjacent to each hinge-rabbet, and has its body und beveled faces covered exteriorly by a plate filmt; is continuous, substantially as and f0r the purpose shown.

3. As a new article of manufacture, a filled watch-case center which is provided with a beveled face adjacent t0 each hinge-rabbet, and such bem1ed face is covered by aplz 1te thab 1's integral with and forms a part of 13118 covering ot' the body of said casecenter, substantially as and for the purpose sei; f01t11.

4. As a new article 0f manufacture {L watehcase center whieh is constructed principally 0f 01 from a base metal, and is providcd Witl1 a beve1ed face adjacenb t0 each hinge-rabbet, and has its body und beveled faces covered by a plate 0f relatively Eine metal which forms a continuous surface over the same substantially as and f01 the purpose shown and described.

In testimony that; I c1uim the foregoing I have hereunto sei; my band this 27th day 0f 55 October, A. D. 1886.
